# Arete AIOS Brand Center > Public visual-design source for Arete AIOS. Use the exact design values and original logo files. Preserve the source material's technical meaning, language, author credits and verified references. Backup base URL for the same public guide and files: https://wisdomblend-eb-brand.pages.dev/. If the custom domain is unavailable, replace the base URL and retain each file path, including /brand.md, /assets.json, /tokens.json and /img/ logo files. ## Start here - [Design specification](https://brand.areteaios.com/brand.md): English visual rules, dark presentation rules and reusable AI brief. - [Original assets](https://brand.areteaios.com/assets.json): Direct logo URLs, dimensions, formats and usage. Download and place the actual files unchanged; do not redraw or generate substitute marks. - [Design tokens](https://brand.areteaios.com/tokens.json): Machine-readable colours, fonts, spacing, shapes and slide rules. - [CSS variables](https://brand.areteaios.com/tokens.css): Importable implementation values. - [Human guide](https://brand.areteaios.com/): English guide with samples, downloads and the copy-ready brief. ## Examples and reusable instructions - [Official website](https://areteaios.com/): Live web layout example. - [Ten-slide reference](https://brand.areteaios.com/examples/presentation/): English example with editable PowerPoint, PDF and offline HTML. - [Existing video](https://www.youtube.com/watch?v=ytaDEKtw9j8): English unlisted walkthrough. Current written typography rules take precedence over this historical recording. - [Portable skill](https://brand.areteaios.com/SKILL.md): Reusable instructions for Arete AIOS materials across formats. This center covers websites, interfaces, presentations, documents, handouts, social content and video. Adapt layouts to each medium without inventing brand values. ## Presentation defaults 16:9, 1920 × 1080 px. Every slide uses #0A121F background, #F9FAFC headings, #C4CBD6 body and #0081FF emphasis. Literata 500–600 for slide titles, Inter for other text, JetBrains Mono only for code, terminals or data. Body text is at least 34 px at this canvas size. One main idea and no more than 45 words per slide. Deliver editable presentation source and PDF. Arete AIOS websites, working interfaces and presentations use dark surfaces throughout. Consult brand.md for the complete rules. If your tool cannot fetch a URL, ask the user to attach brand.md, assets.json and the logo files. Do not claim the guide was read if retrieval failed, and do not guess the design. Save the brief as project knowledge when supported, or reuse it in a new conversation.
